e.g. for 123, the code would see 1 first, then when it sees 2, it would do 1X10 + 2 = 12, and then when it sees 3 it would do 12*10 +3 = 123. It just moves the first number by a tenth place each time. of course if an operator or bracket appears, it resets.
After trying to solve this at timestamp 48:12:91, only having passed 8 test cases out of 46, seeing this straightforward approach and really intuitive code is discouraging me, I cannot lie. I have to keep going, I know, but sometimes I wonder if I am simply incapable of solving some questions. I would like to think that is not the case.
